A PDF-controlled CMap name is passed to `os.path.join()` and `pickle.loads()` after only NUL bytes are stripped, so a hex-encoded absolute path in a crafted PDF's `/Encoding` name can redirect deserialization to an attacker-writable `.pickle.gz` file, giving arbitrary Python code execution with the privileges of the BabelDOC process.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-m8gf-v64p-gfmg","publishedAt":"2026-07-10T19:32:44.000Z","cveId":"CVE-2026-54071","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["BabelDOC@<= 0.6.2 (fixed: 0.6.3)"],"affectedPackageNames":["babeldoc"],"affectedPackageRefs":["pypi:babeldoc"],"affectedVendors":[],"affectedVendorsRaw":["BabelDOC"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.0038,"epssCheckedAt":"2026-10-14T18:05:59.791Z","kevDateAdded":null,"advisoryAliases":["GHSA-m8gf-v64p-gfmg"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-07-10T19:32:44.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.7,"researchCategory":null,"atlasIds":null}}
